What's the most important thing you've learned from your sister? How has she—and your relationship with her—influenced your work?

Lena Dunham: My sister is bold, independent, and not afraid to wear overalls. Some of her first words as a child were "that's not fair," and she's been committed to social justice ever since. She's my hero.

Your sister was a major part of Tiny Furniture. Any plans to have her take on a Girls role?

LD: My mom already made a killer Girls cameo as a mean art dealer! Grace, on the other hand, is far too private to appear on HBO, which is sad because she's a good actor.

Your sister's coming out was obviously an emotional time for you and your family—and you've been honored by the Point Foundation for your work with LGBTQ students. What's your advice to young LGBTQ students? How has your experience with your sister changed your understanding and view on the LGBTQ community?

LD: My sister grew up in an incredibly accepting, liberal community, and coming out still had its challenges, so as a family we are keenly aware of the hardships LGBTQ youth face every day. My advice would be to seek community, seek safe spaces, ask for help from adults you trust, and know that you are brave and your people are waiting out there for you, even when you can't feel them.

How close are you and your sister now?

LD: She's one of my very best friends—and she's my only sister, which is the deepest bond there is.

You've been in what appears to be a really great relationship with Jack Antonoff for a while now. What have you learned is a key element that keeps two people happy together?

LD: I think that it's very important to be with someone who makes you feel like the best version of yourself. In some sense, your partner is a mirror, and you have to like what they're reflecting back at you. Many times we adore someone but hate who we are when we are with them (jealous, needy, scared). To me, that's not real love.

What, if anything, did your mom teach you or tell you about love growing up?

LD: My mother really taught my sister and me to stand strong in our convictions, even—and especially—when met with dissent. She has never compromised her values during her long career. At the same time, she showed us what it meant to be open to change and to consciousness-raising. There is not point in life when it's too late to evolve. What a dreamy combination of lessons!
